panel is displayed.

Click the Apply button to save the change to the device's running-config file.

Disabling IGMP on Individual Ports
By default, when you enable IP multicast on the HP 6208M-SX, all ports on the switch are configured for IGMP. If
you are using active IGMP, all ports can send IGMP queries and receive IGMP reports. If you are using passive
IGMP, all ports can receive IGMP queries.
You can disable IGMP on individual ports if you want to block all IP multicast traffic on those ports. When you
disable IGMP on an individual port, the switch does not forward any multicast traffic out the port, but other ports
can still send and receive multicast traffic.
To disable IGMP on a port, use the following CLI method.
NOTE: You must reload the software after making this configuration change and saving it to the startup-config
file.
USING THE CLI
HP9300(config)# int e 1/5
HP9300(config-if-1/5)# ip-multicast-disable
Syntax: [no] ip-multicast-disable
The command in this example disables IGMP on port 1/5 but does not affect the state of IGMP on other ports.
USING THE WEB MANAGEMENT INTERFACE
You cannot disable IGMP on a port using the Web management interface.
Modifying the Query Interval
The query interval specifies how often the HP 6208M-SX enabled for active IP Multicast Traffic Reduction sends
Group Membership queries.
NOTE: The query interval applies only to the active mode of IP Multicast Traffic reduction.
To modify the query interval, use the following CLI method.
